. center gear 17 will cause the series of gears 16 to travel around within the ring gear 18 and rotate the disk- 12 which in turn will drive the shaft and gear 20 at a much slower speed than that of the sleeve and armature 11, greatly increasing the power of the motor by means of the reduction gears to perform the Work of turning the engine over in starting. As soon as the engine starts, the current to the motor is cut oil in any convenient manner, thus denergizing the magnet to release the dog and permitting the shaft to turn independently of the sleeve and its motor armature.

This construction permits of the use of a motor and a separate generator as they are arranged end to end in longitudinal alinement so that they may be inclosed in a suitable caslng of proper dimension for use in automobile constructions and motion transmitted to and from the same at either or both ends of the casing, due to the fact that the shaft extends entirely through the casing.

Obviously, other means than the planetary gear arrangement may be employed and other changes in construction and arrangement of parts may be made without departing from the spirit of the invention. I do not therefore limit myself to the particular construction shown.

Having thus fully described my invention, what ,I claim is In an engine starter, the combinatlon of a casing, a tubular shaft mounted in the 'casing, a drive shaft extending through and rotatable independently of said tubular.

shaft, a disk secured upon the driving shaft beyond the end of the tubular shaft, a gear on the tubular shaft, planetary gears on the disk the plane of and in mesh with said gear, an internal gear ring in the plane of and in engagement with the planetary gears and having external teeth, and an electrically controlled dog for engaging said external teeth and holding said ring against turning, said dog extending radially in the plane of said gears.

In testimony whereof I aflix my signature in presence of two witnesses.
